How big is your family (Think bigger than biology...)?

I have been preoccupied with this question because it causes us to examine how we define the group of people to which we have a relationship and for which we feel a responsibility.

For example, if your family is as big as your school district, you won't believe in property taxes going into a state pool and distributed to all school districts equally based on need. If your family is as big is your state, you will believe in richer school districts funding poor school districts within the same state.

For example, if your family is as bigger than your country, you may believe that immigrants should be allowed the basic priviledges of U.S. citizens such as in-state tuition to state schools or Medicaid.

If you family ends at your driveway, you may think, "Me for me and you for you; who gives a crap about anybody outside my circle."

Just curious, how big is YOUR family and why?
